If it's not a keeper league, then I think you do this deal. You should be strong in steals so losing Rondo won't hurt. Carter will get close to Rondo's dimes. Jamison is in a contract year and he will give you 8 bds per, offsetting some of the loss of Jefferson's bds. You get mega 3's and scoring as well obviously.

I pulled the trigger on the trade. I wasn't really severely lacking in 3s (only partially), but I was lacking in assists. I didn't want to start Rondo because I had much better players already. Carter helps me in assists and Jamison trades a bit in FG% and obviously blocks, for 3s. My SGs before were Monta, Manu and Foye so I was pretty weak there. As I see it I got 2 starters for one, so it's a win for me.
